The invention discloses a constant-current circuit voltage-dividing isolation and suspension pulse driver, comprising an isolation and suspension pulse driving module and N constant-current modules which are connected in series in sequence. The head end and the tail end of the driver are respectively connected with the positive end HV+ of a DC power supply and a negative end HV- of the DC power supply, wherein N=[1, 2,and the like, I, and the like, n], n>=1, that is, the N constant-current modules comprise a first constant-current module, a second constant-current module, and the like, the ith constant-current module, and the like, and the nth constant-current module. In addition, the principle for determining the N is to ensure any constant-current to operate in a constant-current operating voltage range thereof. The isolation and suspension pulse driver is simple in design, rational in structure, convenient in construction, and good in universality. The pulse driver can overcome deficiency of high-voltage adaptability of an existing pulse driver, and can effectively realize isolation and suspension level switch of pulse signals.
